sTeam provides a technical platform which allows groups of students, lecturers, and any other groups to construct and arrange their individual and cooperative learning and working space. It consists of an object-oriented server connected to a database, and Web, Java, and other (FTP, SMTP, IRC, etc.) clients. The server is event-driven and manages all user objects as well as the communication between the connected clients. Features that were different from most other cooperation tools is the self-organisation and self-administration by the members within the virtual environment.
Wollabot is a modular service bot for IRC channels. It's written entirely in PHP, making it crossplatform and easy to customize. It's not supposed to be guarding channels and does not contain such functionality, thus increasing performance for the tasks it is supposed to do. It comes bundled with a couple of modules (e.g., a PHP function prototype lookup and a Google lookup tool).
The QuoteEngine is an eggdrop TCL script (with an optional PHP-based Web interface) that allows channel users (with the right flags) to store IRC quotes in a MySQL database. Adding, searching, fetching, and deleting from the channel are supported. Multiple channel support is native.
